Although the BAT file is easy to use, its security is too fragile. Anyone can open and view or even modify the content. Is there any handler that fails to convert .batto. .exe or. com, or is still a. BAT file? But others cannot view and modify the content ??? Is there anything like self-encryption? Let's give you a solution. The current solution is as follows: 1. Batch Processing Code How to insert Unicode feature strings Use the istextunicode functi

Base64 encryption algorithm C ++ code implementation, base64 encryption algorithm code The base64 encryption rules are as follows: Base64 requires that each three 8-bit bytes be converted into four 6-bit bytes (3*8 = 4*6 = 24), and then 6-bit bytes be added with two more high 0 values, it consists of four 8-bit bytes. That is to say, the converted string is theor

It seems that the encrypted file is almost twice the size of the original file if there are Chinese characters After encryption. In addition, the execution speed of the encrypted script is several times slower, which may be 10 times slower. I don't know why.

Today, I ran into a different experience with the background encryption results in Windows because strings with newline strings are encrypted. And look for information everywhere. Have tried to change the line to 10, the result or not, and finally in a number of trial and error found in the change to replace the line \ r \ n.Str.replace (/(\n|\r)/g, ' \ r \ n ')You deserve to have!Md5.js encryption with new
